Three-dimensional echocardiography (3DE) enables new views of heart valves and the septa to be imaged. While the previous 3DE system was cumbersome, the recent introduction of live 3DE allowed for routine use of the technique in adult patients. Here, we report our initial experiences in adapting live 3DE and the adult matrix probe to the pediatric population. Thirty-four 3DE examinations were performed on children, aged 1 day to 12 years (n = 23; median 4 years) and fetuses 20-33 weeks in gestation (n = 11; median 25 weeks), many of whom had various congenital heart diseases. The pediatric matrix probe (2-7 MHz) was used for 2D, Doppler, and 3DE. New modalities of the Vision 2007 (Philips) were applied: live, full volume, thick slice, 3D color Doppler, the QLAB system for navigation, and cropping. The pediatric matrix probe allows for complete 2D and 3D echocardiography, and new acoustic windows are now available to perform live 3DE. The higher frequency of the probe increases the 3D image resolution obtained in neonates and fetuses. This advancement allows new views of the aorta, pulmonary valve, septa and intra cardiac anatomy to be captured. Real time 3DE is a feasible method in addition to conventional 2D echocardiography for evaluating congenital heart disease.
三维超声心动图（3DE）能够对心脏瓣膜和间隔进行新视角的成像。尽管先前的3DE系统操作不便，但近期实时3DE的引入使得该技术能够在成年患者中常规使用。在此，我们报告将实时3DE和成人矩阵探头应用于儿科人群的初步经验。对年龄从1天至12岁的儿童（n = 23；中位数4岁）和妊娠20 - 33周的胎儿（n = 11；中位数25周）进行了34次3DE检查，其中许多人患有各种先天性心脏病。儿科矩阵探头（2 - 7兆赫）用于二维、多普勒和三维超声心动图检查。应用了飞利浦公司2007版的新模态：实时、全容积、厚层、三维彩色多普勒、用于导航和裁剪的QLAB系统。儿科矩阵探头可实现完整的二维和三维超声心动图检查，并且现在有了新的声学窗口来进行实时3DE检查。探头的较高频率提高了在新生儿和胎儿中获得的三维图像分辨率。这一进展使得能够获取主动脉、肺动脉瓣、间隔和心脏内解剖结构的新视角。除了传统二维超声心动图之外，实时3DE是评估先天性心脏病的一种可行方法。
